        TinyDB is a lightweight document oriented database optimized for your happiness :)
        It's written in pure Python and has no external dependencies. The target are
        small apps that would be blown away by a SQL-DB or an external database server.
        
        TinyDB is:
        
        - **tiny:** The current source code has 1200 lines of code (with about 40%
          documentation) and 1000 lines tests. For comparison: Buzhug_ has about 2500
          lines of code (w/o tests), CodernityDB_ has about 7000 lines of code
          (w/o tests).
        
        - **document oriented:** Like MongoDB_, you can store any document
          (represented as ``dict``) in TinyDB.
        
        - **optimized for your happiness:** TinyDB is designed to be simple and
          fun to use by providing a simple and clean API.
        
        - **written in pure Python:** TinyDB neither needs an external server (as
          e.g. `PyMongo <http://api.mongodb.org/python/current/>`_) nor any dependencies
          from PyPI.
        
        - **works on Python 2.6 – 3.5 and PyPy:** TinyDB works on all modern versions
          of Python and PyPy.
        
        - **powerfully extensible:** You can easily extend TinyDB by writing new
          storages or modify the behaviour of storages with Middlewares.
        
        - **100% test coverage:** No explanation needed.
        
        To dive straight into all the details, head over to the `TinyDB docs
        <https://tinydb.readthedocs.io/>`_. You can also discuss everything related
        to TinyDB like general development, extensions or showcase your TinyDB-based
        projects on the `discussion forum <http://forum.m-siemens.de/.>`_.
        
        
        Example Code
        ************
        
        .. code-block:: python
        
            >>> from tinydb import TinyDB, where
            >>> db = TinyDB('/path/to/db.json')
            >>> db.insert({'int': 1, 'char': 'a'})
            >>> db.insert({'int': 1, 'char': 'b'})
        
        Query Language
        ==============
        
        .. code-block:: python
        
            >>> User = Query()
            >>> # Search for a field value
            >>> db.search(User.name == 'John')
            [{'name': 'John', 'age': 22}, {'name': 'John', 'age': 37}]
        
            >>> # Combine two queries with logical and
            >>> db.search((User.name == 'John') & (User.age <= 30))
            [{'name': 'John', 'age': 22}]
        
            >>> # Combine two queries with logical or
            >>> db.search((User.name == 'John') | (User.name == 'Bob'))
            [{'name': 'John', 'age': 22}, {'name': 'John', 'age': 37}, {'name': 'Bob', 'age': 42}]
        
            >>> # More possible comparisons:  !=  <  >  <=  >=
            >>> # More possible checks: where(...).matches(regex), where(...).test(your_test_func)
        
        Tables
        ======
        
        .. code-block:: python

            >>> table.insert({'value': True})
            >>> table.all()
            [{'value': True}]
        
        Using Middlewares
        =================
        
        .. code-block:: python

        | **Status:**      *experimental*
        | **Description:** A simple wrapper that allows to use TinyDB as a flat file
                           drop-in replacement for MongoDB.
        
        |
        
        | **Name:**        ``tinyrecord``
        | **Repo:**        https://github.com/eugene-eeo/tinyrecord
        | **Status:**      *stable*
        | **Description:** Tinyrecord is a library which implements experimental atomic
                           transaction support for the TinyDB NoSQL database. It uses a
                           record-first then execute architecture which allows us to
                           minimize the time that we are within a thread lock.
        |
        
        | **Name:**        ``tinydb-serialization``
        | **Repo:**        https://github.com/msiemens/tinydb-serialization
        | **Status:**      *stable*
        | **Description:** ``tinydb-serialization`` provides serialization for objects
                           that TinyDB otherwise couldn't handle.
        
        |
        
        | **Name:**        ``tinydb-smartcache``
        | **Repo:**        https://github.com/msiemens/tinydb-smartcache
        | **Status:**      *stable*
        | **Description:** ``tinydb-smartcache`` provides a smart query cache for
                           TinyDB. It updates the query cache when
                           inserting/removing/updating elements so the cache doesn't
                           get invalidated. It's useful if you perform lots of queries
                           while the data changes only little.

        - Extend API documentation (see `issue #96 <https://github.com/msiemens/tinydb/issues/96>`_).
        
        **v3.1.3** (2016-02-14)
        =======================
        
        - Fix a bug when that breaks the JSONStorage when the ``TinyDB`` instance gets garbagge collected
          (see `issue #92 <https://github.com/msiemens/tinydb/issues/92>`_).
        
        **v3.1.2** (2016-01-30)
        =======================
        
        - Fix a bug when using unhashable elements (lists, dicts) with
          ``Query.any`` or ``Query.all`` queries
          (see `a forum post by karibul <https://forum.m-siemens.de/d/4-error-with-any-and-all-queries>`_).
        
        **v3.1.1** (2016-01-23)
        =======================
        
        - Inserting a dictionary with data that is not JSON serializable doesn't
          lead to corrupt files anymore (see `issue #89 <https://github.com/msiemens/tinydb/issues/89>`_).
        - Fix a bug in the LRU cache that may lead to an invalid query cache
          (see `issue #87 <https://github.com/msiemens/tinydb/issues/87>`_).
        
        **v3.1.0** (2015-12-31)
        =======================
        
        - ``db.update(...)`` and ``db.remove(...)`` now return affected element IDs
          (see `issue #83 <https://github.com/msiemens/tinydb/issues/83>`_).
        - Inserting an invalid element (i.e. not a ``dict``) now raises an error
          instead of corrupting the database (see
          `issue #74 <https://github.com/msiemens/tinydb/issues/74>`_).
        
        **v3.0.0** (2015-11-13)
        =======================
        
        -  Overhauled Query model:
        
           -  ``where('...').contains('...')`` has been renamed to
              ``where('...').search('...')``.
           -  Support for ORM-like usage:
              ``User = Query(); db.find(User.name == 'John')``.
           -  ``where('foo')`` is an alias for ``Query().foo``.
           -  ``where('foo').has('bar')`` is replaced by either
              ``where('foo').bar`` or ``Query().foo.bar``.
        
              -  In case the key is not a valid Python identifier, array
                 notation can be used: ``where('a.b.c')`` is now
                 ``Query()['a.b.c']``.
        
           -  Checking for the existence of a key has to be done explicitely:
              ``where('foo').exists()``.
        
        -  Migrations from v1 to v2 have been removed.
        -  ``SmartCacheTable`` has been moved to `msiemens/tinydb-smartcache`_.
        -  Serialization has been moved to `msiemens/tinydb-serialization`_.
        - Empty storages are now expected to return ``None`` instead of raising ``ValueError``.
          (see `issue #67 <https://github.com/msiemens/tinydb/issues/67>`_.

          `pull request #64 <https://github.com/msiemens/tinydb/pull/64>`_).
        
        **v2.3.2** (2015-05-20)
        =======================
        
        - Fix a forgotten debug output in the ``SerializationMiddleware``
          (see `issue #55 <https://github.com/msiemens/tinydb/issues/55>`_).
        - Fix an "ignored exception" warning when using the ``CachingMiddleware``
          (see `pull request #54 <https://github.com/msiemens/tinydb/pull/54>`_)

        =======================
        
        - Hopefully fix a problem with using TinyDB as a dependency in a ``setup.py`` script
          (see `issue #51 <https://github.com/msiemens/tinydb/issues/51>`_).
        
        **v2.3.0** (2015-04-08)
        =======================
        
        - Added support for custom serialization. That way, you can teach TinyDB
          to store ``datetime`` objects in a JSON file :)
          (see `issue #48 <https://github.com/msiemens/tinydb/issues/48>`_ and
          `pull request #50 <https://github.com/msiemens/tinydb/pull/50>`_)
        - Fixed a performance regression when searching became slower with every search
          (see `issue #49 <https://github.com/msiemens/tinydb/issues/49>`_)

        **v2.2.1** (2015-01-09)
        =======================
        
        - Fixed handling of IDs with the JSON backend that converted integers
          to strings (see `issue #45 <https://github.com/msiemens/tinydb/issues/45>`_)
        
        **v2.2.0** (2014-11-10)
        =======================
        
        - Extended ``any`` and ``all`` queries to take lists as conditions
          (see `pull request #38 <https://github.com/msiemens/tinydb/pull/38>`_)
        - Fixed an ``decode error`` when installing TinyDB in a non-UTF-8 environment
          (see `pull request #37 <https://github.com/msiemens/tinydb/pull/37>`_)
        - Fixed some issues with ``CachingMiddleware`` in combination with
          ``JSONStorage`` (see `pull request #39 <https://github.com/msiemens/tinydb/pull/39>`_)
        
        **v2.1.0** (2014-10-14)

        - Fixed a bug that corrupted data after reopening a database
          (see `issue #34 <https://github.com/msiemens/tinydb/issues/34>`_)
        
        **v2.0.1** (2014-09-22)
        =======================
        
        - Fixed handling of Unicode data in Python 2
          (see `issue #28 <https://github.com/msiemens/tinydb/issues/28>`_).

        =======================
        
        `Upgrade Notes <http://tinydb.readthedocs.io/en/v2.0/upgrade.html#upgrade-v2-0>`_
        
        **Warning:** TinyDB changed the way data is stored. You may need to migrate
        your databases to the new scheme. Check out the `Upgrade Notes <http://tinydb.readthedocs.io/en/v2.0/upgrade.html#upgrade-v2-0>`_
        for details.
        
        - The syntax ``query in db`` has been removed, use ``db.contains`` instead.
        - The ``ConcurrencyMiddleware`` has been removed due to a insecure implementation
          (see `Issue #18 <https://github.com/msiemens/tinydb/issues/18>`_).  Consider
          `tinyrecord <http://tinydb.readthedocs.io/en/v2.0/extensions.html#tinyrecord>`_ instead.
        
        - Better support for working with `Element IDs <http://tinydb.readthedocs.io/en/v2.0.0/usage.html#using-element-ids>`_.

        - Added ``all`` and ``any`` `comparisons on lists <http://tinydb.readthedocs.io/en/v2.0.0/usage.html#nested-queries>`_.
        - Added optional `smart query caching <http://tinydb.readthedocs.io/en/v2.0.0/usage.html#smart-query-cache>`_.
        - The query cache is now a `fixed size LRU cache <http://tinydb.readthedocs.io/en/v2.0.0/usage.html#query-caching>`_.
        
        **v1.4.0** (2014-07-22)
        =======================
        
        - Added ``insert_multiple`` function
